Chevy Colorado Diesel. Boise Springworks pack. (they remove overload leaf and added 5 more... Raises it 1.5"). I might consider putting on Firestone bags for adjusting side to side. We did a 12,000 mile trip to AK and back. Started with just an add-a-leaf.... was happy with the rider so we stopped into Idaho on return. I also put a swat bar on. rock solid. We were heavier than needed...over packed tools etc for every possible problem... way too much. I also Have AT3 Cooper E rated tires they are good.
